Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	dihydropteroate synthetase ^[1] 320 μM
In vitro	Sulfanilamide containing the sulfonamide functional group displays inhibitory activity for dihydropteroate synthetase partially purified from Escherichia coli which normally uses para-aminobenzoic acid (PABA) for synthesizing the necessary folic acid acting as a coenzyme in the synthesis of purine, pyrimidine and other amino acids, exhibiting an IC 50 of 320 μM for dihydropteroate synthetasea and Km of 2.5 uM for PABA. ^[1] This compound shows IC50 of 286.8 μg/mL for recombinant S. cerevisiae strains with wild-type FOL1 genes, but the single mutation ⁵⁵Trp to ⁵⁵Ala or ⁵⁷Pro to ⁵⁷Ser within the putative active site of the fungal DHPS confers resistance to this chemical with IC50 of >800 μg/mL. ^[2] It moderately inhibits the growth of bacterial cells harboring plasmodium falciparum pKOS-pfPPPK-DHPS (His) with IC50 of 380 uM. ^[3]
In vivo	Administration of Sulfanilamide with the dosage of 100 mg/kg/day is effective in the prevention of P. carinii infection in the immunosuppressed rat model. When the dosage of sulfaguanidine and this compound reduced to 10 mg/kg/day, breakthrough P. carinii infection occurs in the rats. ^[4]
